Theory and Calculation of Transient Electric Phenomena and Oscillations (Classic Reprint)

As the result of the increasing importance of the subject and our increasing knowledge, a large part of this book had practically to be rewritten, with the addition of much new material, especially inS ections III and IV. In Section III, the chapters on Final Velocity of theE lectric Field and on High-frequency Conductors have been rewritten and extended. As Section V, an entirely new section ha.s been added, comprising six new chapters. The effect of the finite velocity of the electric field, that is, the electric radiation in creating energy components of inductance and of capacity and thereby effective series and shunt resistances is more fully discussed. These components may assume formidable values at such high frequencies as are not infrequent in transmission circuits, and thereby dominate the phenomena. These energy components and the equations of the unequal current distribution in the conductor are then applied to a fuller discussion of high-frequency conduction. In Section IV, a chapter has been added discussing the relation of the common types of currents: direct current, alternating current, etc., to the general equations of the electric circuit. A discussion is also given of the interesting case of a direct current with distributed leakage, as such gives phenomena analogous to wave propagation, such as reflection, etc., which are usually familiar only with alternating or oscillating currents. A new chapter is devoted to impulse currents, as a class of non-periodic but transient currents reciprocal to the periodic but permanent alternating currents. Hitherto in theoretical investigations of transients, the circuit constants rL Cand ghave been assumed as constant.
